The worldwide attempt to increase the speed of supercomputers merely by increasing the number of processor cores on individual chips unexpectedly worsens performance for many complex applications, Sandia simulations have found.

In less time than the blink of an eye, the Translational Genomics Research Institute's new supercomputer at Arizona State University can do operations equal to every dollar in the recent Wall Street bailout.

Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets.

IBM (NYSE:IBM) said today it will offer remote, $99 “test drives” of Microsoft’s newly launched supercomputer operating system, Windows HPC Server 2008, via its global network of IBM® Computing on Demand facilities.

Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.

The Naval Oceanographic Office (NAVO) Major Shared Resource Center (MSRC) will house a powerful new IBM (NYSE: IBM) supercomputer that will be used principally to support the oceanographic modeling and analysis needs of researchers at the Department of Defense.

IBM (NYSE: IBM) today announced the deployment of Canada's fastest research supercomputer at the Ontario Cancer Institute, University Health Network. The new system will aid in the search for more effective cancer treatments.

IBM's (NYSE: IBM) history-making hybrid supercomputer, built for the National Nuclear Security Administration’s (NNSA) Los Alamos National Lab, burned its way into the TOP500 Supercomputer record book today as the most powerful system in the world – by a wide margin.

IBM and Umeå University announced today that the most powerful Windows-based computer in Europe is being installed at the supercomputer center known as HPC2N. Scientists at HPC2N will use the powerful system – running on a beta version of Windows HPC Server 2008® – for basic as well as applied research.

Less than a week after Los Alamos National Laboratory's Roadrunner supercomputer began operating at world-record petaflop/s data-processing speeds, Los Alamos researchers are already using the computer to mimic extremely complex neurological processes.

In 2006, the Department of Energy’s National Nuclear Security Administration selected Los Alamos National Laboratory as the development site for Roadrunner and IBM as the computer’s designer and builder.

Upgrades to Oak Ridge National Laboratory's Jaguar supercomputer have more than doubled its performance, increasing the system's ability to deliver far-reaching advances in climate studies, energy research, and a wide range of sciences.
